NHibernate

Could not add assembly test

 

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
 <session-factory name="NHibernate.Test">
  <!-- properties -->
  <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
  <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
  <property name="connection.connection_string">server=.;uid=sa;pwd=123456;database=demoTest</property>
  <property name="show_sql">false</property>
  <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
  <property name="use_outer_join">true</property>
  <!-- mapping files -->
  <mapping assembly="test" />
 </session-factory>
</hibernate-configuration>
